Hardness

The Shore Durometer iswidely used to test the hardness of soft materials.A round point indents the material under a fixed force spring and the hardness is displayed on the dial. The instrument can be either hand held or fitted to an optional stand for increased repeatability

The TQC Pendulum Hardness Tester has a lot of unique features that ease defining hardness by the Konig and/or Persoz method . Both methods work on the principle that the damping time of a pendulum oscillating on a sample indicates the hardness.

Used to check the hardness of many materials including plastics, polyesters, leather, and soft metals. When pressure is applied to the device, a point penetrates the material and the degree of hardness is displayed on a dial, which is graduated from 0 to 100.

The buchholz hardness tester is used for measuring the hardness of a coating by indentation of a bevelled disc indenting tool with a sharp edge. The bucholz tester is placed on the coating for 30 seconds and the indentation length is then recorded. The length of the trace is inversely proportional to the hardness.

This simple
sclerometer contains a round tip which is compressed by a spring.
The amount of compression on the spring increases the force as the
tip is pressed into the coating - by varying the force the user
can determine the coating hardness.
